Subject [jira] [Commented] (HADOOP-7455) Introduce HA Service Protocol Interface
Date Thu, 14 Jul 2011 00:39:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13064985#comment-13064985

Suresh Srinivas commented on HADOOP-7455:
-----------------------------------------

?
I thought adding a generic exception to indicate, a directive was given to the service and
it failed to execute it. One of the dangers of adding too many specific excpetions is, verbosity.
Making it too generic is loss of differentiation. Perhaps given that this is just a beginning,
we can start with this. As more HA code goes in, we could see how we are doing.
